新型表面活性剂十六烷基二苯醚二磺酸钠的研制

Preparation of new-type surfactant disodium hexadecyl diphenyl ether disulfonate

在油田的三次采油工艺中,表面活性剂驱油被认为是最有发展潜力的三次采油技术。为降低三元复合驱的综合成本,文中结合采油工艺的需求,采用C16的α-烯烃和二苯醚为原料,通过烷基化和磺化反应合成了十六烷基二苯醚二磺酸钠新型表面活性剂。并分析和验证了该表面活性剂具有优良的性能,为油田三次采油提供了技术支持。

In the third-time oil production technology of the oil field , surfactant flooding is deemed to be the third-time oil production technology of most development potential. To reduce the comprehensive cost of alkali-surfactant-polymer compound flooding , α-olefin and diphenyl ether of C 16 are used as raw materials in this paper based on the requirement of oil production technology , and surfactant disodium hexadecyl diphenyl ether disulfonate as new-type surfactant are synthesized by alkylation and sulfonation reaction. It also analyzed and demonstrated the good performance of this surfactant , and can provide support for the third-time oil production of the oilfield.
